REVIEW
Assaf A Gilad, Mikhail G Shapiro
Biomedical synthetic biology is an emerging field in which cells are engineered at the genetic level to carry out novel functions with relevance to biomedical and industrial applications. This approach promises new treatments, imaging tools, and diagnostics for diseases ranging from gastrointestinal inflammatory syndromes to cancer, diabetes, and neurodegeneration. As these cellular technologies undergo pre-clinical and clinical development, it is becoming essential to monitor their location and function in vivo, necessitating appropriate molecular imaging strategies, and therefore, we have created an interest group within the World Molecular Imaging Society focusing on synthetic biology and reporter gene technologies...

The development of automatic analyzers based on flow techniques involves the use and continuous innovation of fluidic devices. New trends tend toward miniaturization of sophisticated fluidic platforms requiring continuous advances in this field. The availability of a mechanic and electronic workshop together with the know-how to build new fluidic devices provides the tools for the creation of innovative instrumentation and stimulates the creativity of analytical chemists. Thus, in this review we present how to build and use flow-based fluidic devices, together with the tools required, such as computerized controlled lathes, milling machines, laser engraver machines, low-temperature co-fired ceramics technology and 3D printers, highlighting their strong and weak points...

Generating associations is important for cognitive tasks including language acquisition and creative problem solving. It remains an open question how the brain represents and processes associations. The Remote Associates Test (RAT) is a task, originally used in creativity research, that is heavily dependent on generating associations in a search for the solutions to individual RAT problems. In this work we present a model that solves the test. Compared to earlier modeling work on the RAT, our hybrid (i.e., non-developmental) model is implemented in a spiking neural network by means of the Neural Engineering Framework (NEF), demonstrating that it is possible for spiking neurons to be organized to store the employed representations and to manipulate them...

INTRODUCTION: Type 2 Diabetes Mellitus (DM) is on the verge of becoming a pandemic in India. Type 2 DM patient have two to four times increased risk of carotid artery disease. Adipokines have been regarded recently as direct link between diabetes and atherosclerosis. Visceral Adipose Tissue Derived Serine Protease Inhibitor (VASPIN); one of the most recently discovered adipokine, inhibits the proteases responsible for insulin resistance, carotid plaque development and rupture. In literature, few studies have addressed the role of VASPIN in pathogenesis of Acute Coronary Syndrome (ACS) in patients with type 2 DM...

Malignancies that grow in the bone marrow cause a cascade of devastating consequences and are almost always fatal. For researchers to make significant headway in finding cures and treatments for these tumors and the subsequent devastation of cancer-induced bone disease, novel strategies and creative solutions will have to be considered. Great progress has been made in treating hematologic and sold tumor malignancies that ultimately affect the bone marrow, although it is also obvious that multi-disciplinary teams are required to ultimately win the war on cancers that affect the bone...

Quarrelling is a 'routine' activity of the Republic of Letters. This article demonstrates that quarrels played a key role in the field of historical criticism. The contention of this article is twofold. First, it explores the epistemological issues raised by Bayle while reporting the quarrels of the Republic of Letters, and demonstrates their creative potential, thus applying to historiography conclusions drawn by recent research on scientific controversies. It offers a new understanding of scholarly quarrels, here understood as a socially and intellectually structuring activity...

Discovering new medicines is difficult and increasingly expensive. The pharmaceutical industry has responded to this challenge by embracing open innovation to access external ideas. Historically, partnerships were usually bilateral, and the drug discovery process was shrouded in secrecy. This model is rapidly changing. With the advent of the Internet, drug discovery has become more decentralised, bottom-up, and scalable than ever before. The term open innovation is now accepted as just one of many terms that capture different but overlapping levels of openness in the drug discovery process...

The use of virtual simulations in nursing is an innovative strategy that is increasing in application. There are several terms related to virtual simulation; although some are used interchangeably, the meanings are not the same. This article presents examples of virtual simulation, virtual worlds, and virtual patients in continuing education, staff development, and academic nursing education. Virtual simulations in nursing use technology to provide safe, as realistic as possible clinical practice for nurses and nursing students...

Rorschach inkblots have had a striking impact on the worlds of art and science because of the remarkable variety of associations with recognizable and namable objects they induce. Originally adopted as a projective psychological tool to probe mental health, psychologists and artists have more recently interpreted the variety of induced images simply as a signature of the observers' creativity. Here we analyze the relationship between the spatial scaling parameters of the inkblot patterns and the number of induced associations, and suggest that the perceived images are induced by the fractal characteristics of the blot edges...

Alpha-melanocyte-stimulating hormone (α-MSH) is a protein with known capacity for protection against cardiovascular ischemia-reperfusion (I/R) injury. The present investigation evaluates the capacity of α-MSH to mitigate I/R effects in an isolated working rat heart model and determine the dependency of these alterations on the activity of heme oxygenase-1 (HO-1, hsp-32), a heat shock protein that functions as a major antioxidant defense molecule. Healthy male Sprague-Dawley rats were used for all experiments...
